Scrape app permissions for privacy review

Scraping app permissions for a privacy review involves extracting the permissions requested by an app, such as access to camera, location, contacts, microphone, etc., to assess its privacy implications. To carry out this task, you would typically follow these steps:

1. Check App Permissions on App Stores (Google Play or Apple App Store)

Both Google Play and the Apple App Store list the permissions required by an app on their product page. Here’s how you can check:

• Google Play Store:

  1. Open the app’s page on the Google Play Store.

  2. Scroll down to the “Permissions” section to see the list of permissions the app asks for.

• Apple App Store:

  1. Open the app’s page on the Apple App Store.

  2. Scroll down to “Privacy Practices” or “App Privacy” to see the permissions listed under data collection practices.

This method is manual and doesn’t involve scraping.

2. Using Tools for Scraping App Permissions (Advanced)

If you want to automate scraping for app permissions, you would typically use tools or APIs to extract information. Some popular tools are:

• App Store Scraping Tools:
  Tools like App Annie, Sensor Tower, or Data.ai provide APIs that can be used to gather app information, including permissions. However, they often require a subscription.

• APK Extraction for Android Apps:
  You can extract APK files from the Google Play Store and then inspect the permissions using tools like:

  • APKTool: A tool for reverse engineering APK files. After extracting the APK, you can look at the AndroidManifest.xml file, which lists all permissions the app requests.

  • JADX: Another tool that decompiles APK files into Java source code and shows permissions in the manifest.

• App Privacy Policy Scraping:
  You can also scrape an app’s privacy policy (usually hosted on the app developer’s website) for information on permissions and data collection practices. Scraping tools like BeautifulSoup (Python) or Puppeteer (JavaScript) can help with this.

3. Manual Review of Permissions

If you’re doing a privacy review manually, consider the following steps:

• Categorize Permissions: Group permissions based on their purpose (e.g., sensitive data access, user tracking, etc.).

• Assess Necessity: Evaluate whether the app really needs each permission for its core functionality. For example, a photo-editing app should not request access to the user’s contacts.

• Transparency: Review if the app clearly explains why each permission is needed.

• Third-party Access: Check if the app shares data with third parties or tracks users across other apps.

4. API for Scraping Permissions

If you want to automate the process programmatically, you can use an API like:

• Google Play Developer API: It can provide some app details, including permissions.

• Privacy Tools & APIs: Services like Prisma, AppCensus, or Privacy Grade can help automate permission collection and provide an analysis of data practices for apps.

5. Data Collection for Privacy Review

When scraping app permissions, these are the types of permissions to pay attention to for privacy reviews:

• Location: Whether the app requests access to location services (e.g., GPS, network location).

• Camera & Microphone: These can be potential privacy concerns if they are not necessary for the app’s core functionality.

• Contacts & Storage: Apps requesting access to contacts or personal storage data need scrutiny to assess if it’s being used for targeted advertising or sharing with third parties.

• Network Access & Internet: This indicates if an app collects or sends user data over the network.

6. Security Measures & Compliance

• Make sure that the app is compliant with regulations like GDPR, CCPA, or others depending on your location and the app’s region.

• Consider data encryption, whether the app uses secure transmission channels, and its storage policies for personal data.
